Your English is good and it is clear you are an intelligent woman from your posts.  A few corrections:

Sometimes you have to be happy with your position (do you mean situation? Position in English usually refers to a job)

Sometimes you don't know where you are standing.

Sometimes another's view becomes more important than yours

Sometimes someone else's voice drowns out the voice you should be listening to (or distracts you from)

Sometimes you may fail, but the failure has brought you closer to your target.
Sometimes you have gained more than the others acknowledge.
